The Crankshaft Right Oil Seal 20.8X32X6 (91201-K59-A11) is the original replacement engine seal for the Honda PCX 125 (2018-2025). It restores the scooter's lubrication integrity when the factory seal is leaking, hardened, or suffering from blow-by and ensures a high-pressure barrier on the stator side of the crank, shielding internal electrics from oil contamination and preventing the messy drips and oil pressure drops that compromise engine health.
Vetted by our Lead Engineer. Leveraging 30 years of mechanical pedigree, every part is inspected for material density and exact tolerances to ensure a 'Right-First-Time' fit.

Product Overview
This high-quality Original Crankshaft Right Oil Seal 20.8X32X6 is designed to meet or exceed factory performance standards and is suitable for Honda PCX 125 (2018-2025) models.
The crankshaft right oil seal is positioned on the right-hand side of the crankcase, sealing the gap between the rotating crankshaft and the crankcase casing to prevent engine oil from escaping and contaminants from entering. When the seal's rubber lip deteriorates, hardens with age, or becomes damaged by contamination or shaft runout, oil begins to leak from the right-side crankcase, creating an oily deposit on the engine exterior and potentially contaminating the drive side components. This original replacement restores the original crankshaft right-side oil seal integrity, ensuring seamless, secure, and reliable operation of your PCX 125.

Complete Part Guide
The 20.8X32X6 oil seal is a vital defensive component for the 2018-2025 Honda PCX125, situated on the right-hand (stator/fan) side of the crankshaft. A failing seal allows engine oil to weep into the stator housing, which can lead to electrical shorts and a dangerously low oil level. This original Honda part (91201-K59-A11) features a specialized heat-resistant lip to maintain a perfect seal at high RPMs. Stocked at Part Hive's London warehouse, complete your orders before 1 PM to enjoy same-day UK dispatch.
The 20.8x32x6mm crankshaft oil seal (91201-K59-A11) is a critical barrier designed to keep engine oil contained within the right-hand crankcase of the 2018-2025 Honda PCX-125. We frequently find these units failing due to the intense heat soak experienced during heavy stop-start filtering through North London, which causes the rubber lip to harden and weep. Once the seal is compromised, oil begins to contaminate the stator and radiator area, potentially leading to electrical issues or cooling inefficiency. This original Honda replacement part features specific dimensions and internal tension spring engineered to maintain a perfect interface with the rotating crank surface, ensuring a bone-dry engine exterior and prevents the vacuum leaks that lead to erratic idling and poor combustion.
